Used these for an outdoor championship meet in Florida. Wonderful for blocking out the sun and letting me focus on the race. Con- Strap broke right before I got on the block to swim in the finals on the 400! Luckily, I was able to run back to my seat and grab my practice goggles! Of course this did nothing for my focus on the race. I had only worn the goggles a few times so I am disappointed in this. Had to try different straps on the goggles but ended up only using the goggles for the backstroke due to the comfort after we replaced the strap.
